-HJALMAR LINnEsTRoM, or CHICAGO, 'ILLINoIs To all whom it may concern lBe it known that I, HJALMAR LINDE- sTRoM, a citizen of the United States, residing at the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Pressing-Irons, of which the following is a speciiication.

This invention relates to improvements in that type of irons which are heated by a mixture of gas and air supplied internally thereto, when used by tailors and large tailoring establishments for the purpose of pressing garments, lthe seams thereof, and cloth, and Ait consists in certain peculiarities of the construction, novel arbustion thereof and uniform distribution of heat, to the end that the ironingsurface of the iron will be evenly and quickly heated.

Still another object is to provide simple and eiiicient means for preventing the handle and handle-plate from becoming overheated. ff

Other objects and advantages of the invention will be disclosed in the subjoined description and explanation. n l y In the accompanying drawings, v"which serve to illustrate the invention, Figure 1 is a view in side elevation of an liron 'em-- bodying the invention; Fig.72 is a longitudinal central sectional viewV thereof; 3 is a plan sectional view taken on line 3-3 of Fig. 2, looking in thel direction indicated by the arrows; Fig. L1 is a cross sectional view taken on line #1 -4 of Fig. 2; Fig. 5 is a rear end view of the iron, showinga portion of the distributing burner in section, Fig.- 6 is a rear end view of the distributing burner detached from the iron. Fig. 7 is a plan viewtaken on line 7-`7 of Fig. 8 of the lower portion of a modied form of the distributing burner,

PRESSING-IRON.

and F Sy is a cross sectional view taken on line 8 8 of Fig. 7.

` Like numerals of reference refer to cori responding parts throughout the different views of the drawing.

The reference numeral 10 designates the body of the iron, which body is hollow and substantially rectangular in shape, but' with its front end pointed, asis clearly shown in Fig. 3 of the drawings. Within its cavity and at each of the rear 'corners thereof the body 10, is provided with a boss" 11,which extends upwardly from the basev 12 of the body a suitable distance to furnish rests for the distributing burner, which is designated as a whole by the reference numeral 13, and which. burner is substantiallyrectangular in shape, and has at its front end a downwardly and forwardly extendedangle-foot 14 to rest on the base 12 of the bodyso as to support the front end of the burner. The front portion of the foot 14 is formed with a recess ljto receive a lug 16, with which the body 10 is provided within its cavity at the lowerportion of the front end thereof. rEach side of the body 10 is provided just above the 'base 12, with a series of openings 17 for the admission of air to the interior ofthe body, and at its upper portion and on one side thereof the body is provided 'with `openings 18, which are also rfor the passage of air. These latter openings are by preference located on that side ofthebody opposite the operator in order that the heated air passing therethrough rmay be' directed from him.

soy

As is clearly shown in Fig. the burner'A- 13 isprovided with parallel channels 19 20 vandV21, and the channels'20 and 21 extendk almost entirely the length of the body, i while 'the channel 19 lcommunicates with ya cross channel 22, which communicates at its f endsfwith the

channels

20 and 21, which lat-1 ter are provided in their lower surfaces with perforations23`,for the escape of the* mixtureof air and gas. The tube or channel 19, has at its rear end an extension 24, which is externally screw threaded to vengage a mixing member 25, which is'cylindrical in shape, and has in its outer end 'a series ofopenings 26, .for the passage of air into the cavity of the mixing member.

Mounted around the member 25 is a sleeve 27, which will direct air into the openings 26, as is obvious. Screwed into a suitable opening in the outer portion of the mixing member 25, is a pipe 28, which may be provided with a valve 29, for regulating the flow of gas through said pipe. This pipe may be connected to a supply of gas by means of the flexible tube 30 and in the ordinary or any well-known manner.

As shown in the different views of the drawings, the cavity of the body 10 is closed by means of a plate, which consists of two

metal plates

31 and 32, with a layer of asbestos' 33 or other non-heat conducting material interposed between said plates. Resting on the non-heat conducting plate is a handle plate 34, which is provided at each of its corners with a depending lug 35, to rest on the plate 31, and said plates are secured to the body 10, by means ofscrews 36, located in the corners of the plates and seated in suitable openings in the body 10, near its corners.

Extended through the central portion of the handle-plate 3l, is a screw bolt 37, which also passes through a suitable opening in the cover plate of the body, and rests at its lower end on a cross piece 38, of the burner, by which means the latter is held firmly in place within the body of the iron. To prevent any lateral movement of the burner 1 3,

within the iron body, said burner is provided at its rear portion and on each side thereof with an extension 39, which rest against the inner surfaces or corners of the iron body, as will be readily understood by reference to Fig. 3 of the drawings.

Located in the inner end of the pipe 28, is a jet-nozzle 40, which extends into the outer portion of the tubular part 24 of the channel 19, for the discharge of gas into and through said channel, in which operation it will be understood that a suction within the cavity of themember 25 will be created, so as to draw. air through the openings 26, to be 4mixed with the gas as it passes the passageways of the burner. The handle plate 34 is provided with a pair of uprights .L1,y\7l 1ich are connected at their upper ends by means of a handle I12, of wood or other suitable material, -and by which means the iron may be manipulated. .y

In Figs. 7 and 8 is shown the modification in the construction 4of the distributing burner, lwhich modified form is more particularly intended to be used in connection with small sad-irons for household purposes,

. but it will be understood that the same principle of distributing the fuel or mixture is involved in both of the constructions, and furthermore, I desire it to be understood that the distributing burner 13 can be made of two counterpart pieces in a similar manner to those shown in the modified construction. In this modification the burner is formed of two pieces 13a, which are counterparts of one another, each having a central conduit 19 into which the gas and air mixture is discharged in a manner similar to that shown in Fig. 3 and above described.

On each side of the conduit or channel 19a,

each of the pieces 13 is formed with longitudinally extending channels 2Oa and 21,

which communicate with one another at` and for this reason, in some instances, I may y construct the burner 13 of two counterpart pieces.

From the foregoing and by reference to the drawings, it will be readily understood and clearly seen, that by supplying gas through the tube 30, pipe 28, and jet-nozzle 4:0, to the burner, a mixture of air and gas will be produced by. reason of the air entering through the openings 26 of the mixing chamber, and that the said mixture will pass downwardly through the openings 23 inthe burner 13, and openings 23a when the burner 13a is used, where it can be ignited by the means of a match inserted in the rear end of the body beneath the burner. As the mixture is directed downwardly against the base or ironing surface 12 and throughout almost its entire length, it is obvious that .said portion of the iron will be lquickly and uniformly heated, and that as air will be supplied to the cavity of the iron body through the openings 17 and rear portion of saidl body,y it is manifest that complete combustion of the mixture will take place.

I-Iaving thus fully described my invention, what I claim as new and desire to secure byyLetters Patent, is-

1. AnI iron consisting of a hollow body having an opening'in one of its ends and provided lnear said end with bosses extended upwardly from the bottom, a lug at vthe lower inner portion of the other end of the body, a distributing-burner horizontally located within the body and having at one of its ends a foot to engage said lug and at its other end extensions to rest on the said bosses, said burner having a pair of parallel and perforated conduits extended longitudinally therein and also having at one of its ends a conduit intermediate the parallel con, duits but communicating therewith at 'its ,inner end, means to force the burner against said bosses, and a fuel supply pipe connected to the outer end of the intermediate conduit.
